Jason --> 126/6 = 21 pages per hour
joe --> 115/5 = 23 pages per hour
joe reads 2 more pages per hour
hope this helps :)
Answer:
slope = 1/3
explanation:
- recall the formula to find slope:
- Here given ( dotted ) coordinates: (4,1),(-2,-1)
Steps:
<u>Using the formula:</u>
1st pic
It's a rhombus
- <span>None of the angles are 90 degrees (can't not be rectangle or square)
- Opposite angles are equal
Top triangle
180 - ( 72 + 72 )
=180 - 144
= 36
same as bottom triangle....
-----------------------------------
2nd pic.
Rhombus...
opposite angles are equal
so m<1 = m<2 = 160
180 - 160 = 20
m< 3 = 20/2 = 10
answer
</span>m<2 = 160
m<3 = 10<span>
-----------------------------
3rd pic.
</span> <span>isosceles trapezoid
</span>
<span>The legs are congruent by definition
</span>
so AB = CD
7y - 4 = 8y - 18
7y - 8y = -18 + 4
- y = -14
y =14
answer y = 14
-----------
pic 4
A(-5, -1), B(-9, 6) C (-1, 5) D(3,-2)
A(-5, -1) and C (-1, 5) ---find slope of 1st pair
slope = (5 + 1)/(-1 + 5) = 6/4 = 3/2
B(-9, 6) D(3,-2)---find slope of 2nd pair
slope = (-2 -6)/(3+9) = -8/12= -2/3
slope of 2nd pair (-2/3) is negative and reciprocal of the 1st pair (3/2)
so it's perpendicular
Answer:
Me when I don't have no money
Subtract the difference in age from the total:
87 - 15 = 72
Divide by 2:
72 / 2 = 36
Sydney is 36 years old
Devaughn is 15 years older: 36 +15 = 51 years old
51 + 36 = 87
